Hi Linus, As mentioned in the first pull request, there was a later batch as well. This contains fixes to the stuff that already went in, cleanups, and a few later additions. In particular, this pull request contains: - Cleanups/fixes/unification of the submission and completion path (Pavel,me) - Linked timeouts improvements (Pavel,me) - Error path fixes (me) - Fix lookup window where cancellations wouldn't work (me) - Improve DRAIN support (Pavel) - Fix backlog flushing -EBUSY on submit (me) - Add support for connect(2) (me) - Fix for non-iter based fixed IO (Pavel) - creds inheritance for async workers (me) - Disable cmsg/ancillary data for sendmsg/recvmsg (me) - Shrink io_kiocb to 3 cachelines (me) - NUMA fix for io-wq (Jann) Please pull! git://git.kernel.dk/linux-block.git tags/for-5.5/io_uring-post-20191128 ---------------------------------------------------------------- Dan Carpenter (1): io-wq: remove extra space characters Hrvoje Zeba (1): io_uring: remove superfluous check for sqe->off in io_accept() Jann Horn (2): io_uring: use kzalloc instead of kcalloc for single-element allocations io-wq: fix handling of NUMA node IDs Jens Axboe (23): io_uring: io_async_cancel() should pass in 'nxt' request pointer io_uring: cleanup return values from the queueing functions io_uring: make io_double_put_req() use normal completion path io_uring: make req->timeout be dynamically allocated io_uring: fix sequencing issues with linked timeouts io_uring: remove dead REQ_F_SEQ_PREV flag io_uring: correct poll cancel and linked timeout expiration completion io_uring: request cancellations should break links io-wq: wait for io_wq_create() to setup necessary workers io_uring: io_fail_links() should only consider first linked timeout io_uring: io_allocate_scq_urings() should return a sane state io_uring: allow finding next link independent of req reference count io_uring: close lookup gap for dependent next work io_uring: improve trace_io_uring_defer() trace point io_uring: only return -EBUSY for submit on non-flushed backlog net: add __sys_connect_file() helper io_uring: add support for IORING_OP_CONNECT io-wq: have io_wq_create() take a 'data' argument io_uring: async workers should inherit the user creds net: separate out the msghdr copy from ___sys_{send,recv}msg() net: disallow ancillary data for __sys_{send,recv}msg_file() io-wq: shrink io_wq_work a bit io_uring: make poll->wait dynamically allocated Pavel Begunkov (15): io_uring: break links for failed defer io_uring: remove redundant check io_uring: Fix leaking linked timeouts io_uring: Always REQ_F_FREE_SQE for allocated sqe io_uring: drain next sqe instead of shadowing io_uring: rename __io_submit_sqe() io_uring: add likely/unlikely in io_get_sqring() io_uring: remove io_free_req_find_next() io_uring: pass only !null to io_req_find_next() io_uring: simplify io_req_link_next() io_uring: only !null ptr to io_issue_sqe() io_uring: fix dead-hung for non-iter fixed rw io_uring: store timeout's sqe->off in proper place io_uring: inline struct sqe_submit io_uring: cleanup io_import_fixed() fs/io-wq.c | 187 ++++++---- fs/io-wq.h | 63 +++- fs/io_uring.c | 776 ++++++++++++++++++++++------------------ include/linux/socket.h | 3 + include/trace/events/io_uring.h | 16 +- include/uapi/linux/io_uring.h | 1 + net/socket.c | 214 +++++++---- 7 files changed, 757 insertions(+), 503 deletions(-) -- Jens Axboe
